Using the electron configuration flow diagram below what is the correct electron configuration for chlorine atomic number 17

Cl₁₇ = 1s² 2s² 2p⁶ 3s² 3p⁵

Explanation:

Electronic configuration:

Cl₁₇ = 1s² 2s² 2p⁶ 3s² 3p⁵

Properties of chlorine:

Chlorine is present in group seventeen.

It is halogen element. its atomic number is seventeen.

It has seven valance electrons.

It is greenish-yellow irritating gas.

Its melting point is 172.2 K

Its boiling point is 238.6 K

It is disinfectant and can kill the bacteria.

It is also used in manufacturing of paper, paints and textile industries.

When combine with hydrogen it form acids.

H₂ + Cl₂  → 2HCl

it is highly electronegative and most reactive element.

When combine with metals it form salts such as sodium chloride, magnesium chloride.

2Na + Cl₂  →  2NaCl

Mg + Cl₂ → MgCl₂

explanation:

the largest database of organic compounds lists about 10 million substances, which include compounds originating from living organisms and those synthesized by chemists. the number of potential organic compounds has been estimated at 1060—an astronomically high number. the existence of so many organic molecules is a consequence of the ability of carbon atoms to form up to four strong bonds to other carbon atoms, resulting in chains and rings of many different sizes, shapes, and complexities. the simplest organic compounds contain only the elements carbon and hydrogen, and are called hydrocarbons. even though they are composed of only two types of atoms, there is a wide variety of hydrocarbons because they may consist of varying lengths of chains, branched chains, and rings of carbon atoms, or combinations of these structures. in addition, hydrocarbons may differ in the types of carbon-carbon bonds present in their molecules. many hydrocarbons are found in plants, animals, and their fossils; other hydrocarbons have been prepared in the laboratory. we use hydrocarbons every day, mainly as fuels, such as natural gas, acetylene, propane, butane, and the principal components of gasoline, diesel fuel, and heating oil. the familiar plastics polyethylene, polypropylene, and polystyrene are also hydrocarbons. we can distinguish several types of hydrocarbons by differences in the bonding between carbon atoms. this leads to differences in geometries and in the hybridization of the carbon orbitals.

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.
